Bridge crane is a lifting equipment that is horizontally mounted above workshops, warehouses and material yards for material lifting. Because its two ends are located on tall concrete columns or metal brackets, it looks like a bridge, so it is named bridge crane. The bridge is the main load-bearing structure of the bridge crane, which consists of the main beam, end beam, walkway and other parts. The main beam usually adopts a box structure or truss structure, which has high strength and rigidity and can bear the weight of the lifting heavy objects. The end beam is connected to the two ends of the main beam, so that the bridge forms a whole and is supported on the track by wheels. The walkway is installed on both sides of the main beam for operators to walk and repair equipment.

Bridge cranes are widely used in machinery manufacturing, metallurgy, mining, railways, ports, construction and other industries. They are important equipment that is indispensable in modern industrial production and logistics transportation. In machinery manufacturing workshops, it is used to lift raw materials, parts and finished products; in metallurgical plants, it can be used to lift high-temperature heavy objects such as steel ladles and iron ladles; in ports, it can carry out cargo loading and unloading operations.
